  • Publication number: 20160111629
    Abstract: A method for fabricating an STT-MRAM integrated circuit includes forming a fixed layer over a bottom electrode layer, forming a silicon oxide layer a hardmask layer over the fixed, and forming a trench within the silicon oxide and hardmask layers, thereby exposing an upper surface of the fixed layer and sidewalls of the silicon oxide and hardmask layer. The method further includes forming a conformal barrier layer along the sidewalls of the silicon oxide and hardmask layers and over the upper surface of the fixed layer, such that the conformal barrier layer comprises sidewall portions adjacent the sidewalls of the silicon oxide and hardmask layers and a central portion in between the sidewall portions and adjacent the upper surface of the fixed layer. The method further includes forming a free layer between the sidewall portions of the barrier layer and over the central portion of the barrier layer.

  • Publication number: 20160087197
    Abstract: Non-volatile resistive random access memory crossbar devices and methods of fabricating the same are provided herein. In an embodiment, a non-volatile resistive random access memory crossbar device includes a crossbar array including a bitline and a wordline. A hardmask that includes dielectric material is disposed over the bitline. The hardmask and the bitline include a first sidewall. A memory element layer and a selector layer are disposed in overlying relationship on the first sidewall of the bitline and hardmask. The memory element layer and a selector layer are further disposed between the bitline and the wordline, to form a first memory element and selector pair.

  • Patent number: 9263665
    Abstract: A method of fabricating a vertical two-bits per cell STT MRAM for high density storage includes forming a bottom electrode within an interlayer dielectric (ILD) layer, forming an anti-ferromagnetic (AF) layer over the bottom electrode, and forming a fixed layer along sidewalls of the AF layer. The method further includes forming a tunnel layer along the fixed layer, forming a free layer along the tunnel layer, and forming a top electrode along the free layer and over an upper surface of the AF layer.

  • Publication number: 20160028009
    Abstract: A non-volatile memory device and a manufacturing method thereof are provided. The memory device includes a substrate, a lower cell dielectric layer with gate conductors and a body unit conductor disposed on the lower cell dielectric layer and gates. Memory element conductors are disposed on the body unit and lower cell dielectric layer. An upper cell dielectric layer may be on the substrate and over the lower cell dielectric layer, body unit conductor and memory element conductors. The upper cell dielectric layer isolates the memory element conductors.
